Industrial maleic anhydride: the implementation of GB / T 3676-2008 standard)
Maleic anhydride, also known as maleic anhydride, maleic anhydride, 2,5-furandione and so on. Oblique crystal colorless acicular or lamellar crystals. Has a strong stimulating odor, soluble in ethanol, ether and acetone, insoluble in petroleum ether and carbon tetrachloride. Maleic acid with hot water. Mainly used in the production of unsaturated polyester resin, alkyd resin, pesticide malathion, high efficiency and low toxicity pesticide 4049, long-acting iodine amine raw materials. Is also a paint, Malay Rosin, polymaleic anhydride, maleic anhydride - styrene copolymer copolymer monomer, but also the production of ink additives, paper additives, plasticizers, tartaric acid, fumaric acid, tetrahydrofuran and other organic chemical raw materials .
Appearance: white flaky crystal, powdery, acicular, flaky, pelleted, stick-like, lumpy or melted material, with a strong stimulating odor
The relative density: 1.480
Melting point: 52.8 ° C
Boiling point: 202.2 ° C
Flash point (open cup): 110.0 ℃
In the lower temperature (60-80 ℃) easier to vaporize, soluble in alcohol, ether and acetone, deliquescent easily generate maleic acid.
